In File Options, is a box on the Open/Close tab labeled "When opening this file". In the bottom of this box is a check box labeled "Perform Script" and the name of the script should show to the right. If you are using FileMaker 11, you can click the specify button, then pull down the gear menu to select Edit to open and review the script. In older versions, you'd have to make a note of the script name and find it in Manage |Scripts.
